    Troubleshooting Directions

    Note:

    These troubleshooting steps only apply to LogListener 2.2.4 or later. If you’re using an earlier version, see Troubleshooting Earlier LogListener Versions.

    1. Use the LogListener diagnostic tool

    This tool helps you quickly check the LogListener operation, heartbeat and configuration.
    Run the following CLI commands.

    /etc/init.d/loglistenerd check
    

    The following output indicates that LogListener is running properly.

    LogListener heartbeat exception

    If the result returns “[ERROR] check loglistener heartbeat fail”, it indicates that LogListener has a heartbeat exception.

    Many causes can lead to a LogListener heartbeat exception. Possible causes include:

    • Network error
    telnet <cls domain name> 80
    

    Check the network connectivity. For more information about the CLS domain name, see Available Regions.

    • Incorrect key

    To check the LogListener key, access the LogListener installation directory and run the following command.

    grep secret etc/loglistener.conf
    

    2. Check for the IP address of the machine group

    Check that the IP address added to the machine group is the one configured on LogListener during installation. Run the following command to check the IP address configured on LogListener.

    grep group_ip etc/loglistener.conf
    

    Log in to the CLS console, and select Server Group in the left sidebar. On the Server Group Management page, view and verify that the IP address of the machine group is the same as that configured on LogListener.
